Title: Dual microprocessor electronic trip unit for a circuit interrupter
Inventor: SALETTA GARY FRANCIS
IPC: H02H3/093
Filed: 1999-04-06
Abstract: An electronic trip unit having two microprocessors one of which monitors the load voltage and current within the normal operating range and performs the metering and delayed trip algorithms associated with that range. A second microprocessor monitors the load current for excursions outside the normal operating range and processes those algorithms and functions associated with the instantaneous and overcurrent trip protection modes of the trip unit. Each microprocessor receives inputs representative of the monitored current that are scaled to a different factor corresponding to the range the microprocessors are assigned to monitor. In one embodiment the electronic trip unit is controlled by a master controller and in turn controls a number of accessory devices, wherein one of the microprocessors is a slave to the master controller network and the other microprocessor is a master to the accessory slave network. The microprocessors communicate with each other and either one can trip the circuit on detection of a fault condition.
Patent CA-2268732-A1 (CA)
Inventor: MERRITT RICHARD C
IPC: A63B69/18
Filed: 1999-04-07
Abstract: As an aid for teaching people to waterski, the waterski training bar (or ski bar) is known to have an attachment method to the front of the skis and a attachment method to the ski rope to aid a novice person to be able to ride on the skis without the normal requirement of strength and skill. In this invention, a training bar is secured to the front of the skis to keep the skis separated the correct distance and allow the pulling force of the boat to be transferred to the skis directly. The rope then continues to the skier from the ski training bar where it is easily attached, so the handle can be set at the correct distance for the skier and thus provide stability. The bar can be easily attached or removed from the skis, and a regular waterski rope can be easily attached or removed from the bar and adjusted for various height skiers.

Title: Method and apparatus for providing high speed data communications in a cellular environment
Inventor: ZEHAVI EPHRAIM
IPC: H04J13/00
Filed: 1997-10-27
Abstract: A method and apparatus for transmitting digital data in a cellular environment. Adjacent cells of the cellular system (1 and 2A-2F) are prevented from simultaneously transmitting data. Because the noise from transmission of adjacent cells is a primary source of interference, the transmission rate of power limited base stations (1-3) can be dramatically increased when the noise from adjacent cells is eliminated. The transmissions to each subscriber station (6) are made at a fixed transmission power level. However, the data rate of transmitted signals differs from one subscriber station (6) to another depending the path loss differences. In a first exemplary embodiment, the data rate of transmissions to a subscriber station (6) is determined by selecting an encoding rate for the transmitted signal while holding the symbol rate constant. In a second exemplary embodiment, the data rate of transmission to a subscriber station (6) is determined by selecting a modulation format for the transmitted signal which directly changes the symbol rate of transmission to a subscriber station (6).

Title: Water pressure posthole digger
Inventor: SIKES JARED A
IPC: E21B7/18
Filed: 1999-04-27
Abstract: A water pressure operated posthole digging tool.      The tool includes a vertically elongate pipe with an enlarged mandrel member having a generally circular cross section mounted on its lower end, and means for connecting the upper end of the conduit to a source of water pressure.      The water pressure is discharged through an open end at the bottom of the mandrel. member, so that soil is dislodged at the bottom of the posthole bore. The flow of water then passes upwardly through the annular cavity around the sides of the mandrel member so as to scour out of the sides of the bore. The lower end of the mandrel member is tapered so as to accelerate the flow of water as this passes into the annular cavity around the body, and upper taper slows the flow as it exits the cavity and flows up the excavated bore. The mandrel member may be formed of solid plastic material.

Inventor: HOFEREK DUSAN M
IPC: B65D25/04
Filed: 1999-06-22
Abstract: For a recycle box divider (black box recycle implies recycling cardboard and paper goods and blue box recycle implies recycling glass, metal and plastic goods), it consists of only one flat rectangular piece (A) with clips (1) on both sides of the top which latch onto the lip of the recycle box (black or blue recycle box), and two tabs (2) on the bottom to act as stabilizers to hold the bottom in place as well as offset rails (3) near the centre which run from top to bottom; also to conform to different sized recycle boxes, the larger divider (A) will be available to be re-sized, meaning that two parts will be joined together so that the divider (A) can slide further open or closed so as to make it wider or more narrow. Another smaller rectangular piece (B) can be attached perpendicularly to the larger divider (A) by clipping it onto the guide rail (3) of the larger divider (A). Similarly, the smaller divider (B) will be available to be re-sized, meaning that two parts will be joined together so that the divider (B) can slide further open or closed so as to make it wider or more narrow, again to conform to different sized recycle boxes. Note that none, one, or two of the smaller dividers (B) may be used in conjunction with the larger divider (A) at any time. When no smaller dividers (B) are in place, but only the larger divider (A) is in place, it divides the recycle box into two halves for separating recycled goods. When one smaller divider (B) is in place along with the larger divider (A) in place, it divides the recycle box into 3 compartments, namely one half and two quarters of the size of the recycle box, which is used for separating recycled goods. Finally when two smaller dividers (B) are in place along with the larger divider (A) in place, it divides the recycle box into 4 compartments, namely four equal quarters of the size of the recycle box, which is used for separating recycled goods.

Title: Atmospheric-pressure plasma jet
Inventor: SELWYN GARY S
IPC: H05H1/46
Filed: 1998-01-23
Abstract: A .gamma.-mode, resonant-cavity plasma discharge (18) that can be operated at atmospheric pressure and near room temperature using 13.56 MHz rf power is described. Unlike plasma torches, the discharge produces a gas-phase effluent no hotter than 250 °C at an applied power of about 300 W, and shows distinct non-thermal characteristics. In the simplest design, two concentric cylindrical electrodes (14, 20) are employed to generate a plasma in the annular region therebetween. A  "jet" of long-lived metastable and reactive species (22) that are capable of rapidly cleaning or etching metals and other materials is generated which extends up to 8 in, beyond the open end of the electrodes (14, 20). Arcing is prevented in the apparatus by using gas mixtures containing He, which limits ionization, by using high flow velocities, and by properly shaping the rf-powered electrode (14). Because of the atmospheric pressure operation, no ions survive for a sufficiently long distance beyond the active plasma discharge to bombard a workpiece, unlike low-pressure plasma sources and conventional plasmas.

Patent CA-2287807-A1 (CA)
Inventor: MECOZZI WALTER P
IPC: E04B1/61
Filed: 1999-11-01
Abstract: A wall panel assembly with a sealed joint. The sealed joint is virtually airtight even in an enclosure having an ambient air pressure substantially greater than the air pressure outside the enclosure, such as an air handling cabinet. Each joint is comprised of two abutting looped joint edges in combination with a Y-shaped seal. The looped joint edge provides added structural rigidity to the panels, and the enlarged looped ends on the joint edges enclose and protect the seal therebetween from exposure to the elements. The seal itself not only withstands positive internal air pressure but is actually improved thereby. Abutting joint edges of adjacent wall panels create a narrow channel for receiving the longitudinal flange portion of the seal, and a broader V- shaped channel to receive the enlarged body portion of the seal. In this way, the body portion of the seal is seated in a channel so that internal pressure exerted against the seal will cause the seal to appressingly engage the channel. Thus, increased internal air pressure improves the sealed joint rather than compromising it. The seal can be provided with a longitudinal slit for receiving the edge of internal divider panels. Adjacent wall panels are joined by fasteners intersecting the outwardly extending looped portions of the joint edges. In this way, the fasteners are accessible from the outside, and the integrity of the seal is preserved.
